HAT-MATRIX.

To all whom it may concern:

Be it known that I, LESLIE STEvnNs, a citizen of the United States,residing at Glen Ridge, county of Essex, State of New Jersey, haveinvented certain new and useful Improvements in Hat-Matrices, of whichthe following is a full, clear, and exact description.

My invention relates to hat forming machines, and particularly to animproved matrix, so-called.

The object of the invention is to provide a two-part matrix of improvedconstruction, by the use of which superior results may be obtained. Theconstruction is also such that the two parts are effectivelyinterlocked, so that there is no danger of separation which, ifpermitted, would result in the formation of a line or ridge on the brimof the hat.

My improved matrix is formed in the main of an insulating materialinstead of metal, as heretofore. A distinct advantage is derived in theuse of such a matrix because, where the brim has been properlycontoured, if the matrix is of a character to retain the heat, it willnot permit the brim to cool sufliciently while thereon. By my inventionthe heat is not retained. As a re sult, the brim cools quickly, takes aset and the matrix may be removed without danger.

In the accompanying drawings, Figure l is a top plan view; Fig. 2 is arelatively enlarged section on the line 0000 of Fig. 1, broken away;Fig. 3 is an end view of one of the parts, broken away; Fig. 4C is a topplan view of one end of the matrix and illustrating a modification,broken away; Fig. 5 is a cross section on the plane of the line zz ofFig. 4, broken away; Fig. 6 is an end view of one of the parts shown inFig. 4, broken away.

12 represent two opposite side sections of a matrix, the same being inthe main of wood or other insulating material which, in the preferredform, is treated with a water-proof material. These sections aredetachably connected at each end by interlocking buffer plates 6-7. Onthe face of one of these plates, for example 6, is a lip or projection8, forming a groove or recess to the rear of it. 10 is a lip on theplate 7 arranged to enter the said recess and interlock with thecompanion plate 6 in such a Specification of Letters Patent.

manner as to hold these two sections positively against separation, thusguaranteeing a smooth forming surface. 3 is a supporting plate and 44=are pins carried thereby and arranged to enter corresponding recesses inthe sections 1-2 to prevent lateral displacement. The bufier platesserve not only as interlocking devices, but by extending from edge toedge of said sections and being flush therewith, they protect thesurface upon which the hat is formed from chipping or abrasion whichwould, if it were permitted, injure the contour of the hat material. Theinterlocking buffer plates, therefore, perform the double function ofproviding protecting buffers, as well as interlocking devices, thusmaking it possible to employ for the matrix sections light material,such as wood. As already indicated, wood being of low conductivity, whenthe hat material is applied to the matrix and formed thereon with heat,this heat will not be absorbed to any great extent and retained for anylength of time by the matrix itself. Hence, when the heat used informing is removed, the formed hat material quickly cools and becomesset so that the matrix may be taken out' without danger of injuring saidshape. By the employment of my improved matrix much greater speed willbe attained in the manufacture of hats.

In the modification shown (see Figs. 4. to 6), 1, 2, 3 and 4 representthe side sections, base and retaining pins, respectively, as before. Thebuffer blocks are represented by 6 7, the same being suitably secured totheir respective side sections, one of the same having a retainingrecess of modified form, indicated at 9 (Fig. 6). The sides of thisrecess are undercut so as to permit a dovetailed interlocking projection8 on the other plate to enter. This recess and dovetailed projection arepreferably tapered, as shown in Fig. 6.

What I claim is:

1. In a hat matrix, two separable sections formed of material of lowconductivity, protecting interlocking buffer plates at the ends of saidsections, said buffer plates extending from edge to edge of saidsections and flush with the forming surface thereof.

2. In a hat matrix, two separable sections, a plate secured to each endof each section, said plates being formed to interlock with one anotherand to protect the adjacent eX- I ing a projection arranged to entersaid posed edges of the sections at the meeting groove for the purposeof securing said in- 10 points thereof. 1 I terlocking of the parts.
